An age appropriate sex education is needed at all ages starting from the kindergarten.  Talks about good touch,  bad touch,  safe people need to be addressed to very young children as they are more vulnerable to abuses. 

Yes you are right, From kinder garden it is only about telling kids about good touch and bad touch. Here in Ganganagar before one month a sex abuse case with small kid found. Driver of school van done this evil deed.

Actually sex education need not be treated as a separate topic till the child reaches around puberty. But there are so many things which should be a part of bringing up by parents and teachers on a day to day basis. Talking about it on a regular basis as a matter of fact in an age appropriate way is must. But unfortunately in our culture we hush hush such things as there is a social taboo and hesitation. The child is naturally curious to know and explore. That makes him more vulnerable to falling victim to other strangers who can be a sex predator. So getting the right information from a right source in a right way is needed to avoid them from falling prey to mishappenings.
